Abstract
The present invention relates to a regenerating agent for renewing an old asphalt road surface, which is obtained by the following steps: fatty acid waste is extracted for removing impurities according to a proportion; pure liquid is obtained after precipitation; anthracene oil or turpentine waste or petroleum resin is added to be heated and agitated to a certain temperature and be mixed into a whole; then the regenerating agent is obtained. When the present invention is used, the old asphalt road surface is loosened in a digging mode and crushed; after the crushed dregs of the road surface are heated to a certain temperature, the regenerating agent is added into the crushed dregs of the road surface to be uniformly agitated and paved on the road surface, and then the purpose is obtained. The technological process of the technology is simple. Large-scale circular track tests (B22-100 axle load 945 thousand axle times) prove that the asphalt road surface after regeneration has the advantages of good stability and strong wheel-track resistance.
Description
The invention belongs to a kind of regenerating reactivating agent that old asphalt pavement is overhauled that is used for.
Existing old asphalt pavement is overhauled technology, and main the employing excavates broken post-heating with old asphalt pavement, mixes the new pitch of 5-10% bitumen aggregate ratio, mats formation into new bituminous pavement after the stirring.Because only carrying out physical property with old aged asphalt, mixes new pitch, if old pitch does not belong to ageing property, but when influencing pavement destruction because of sub-surface intensity is bad, new and old pitch mixed cause bitumen aggregate ratio (pitch and building stones weight ratio) excessive easily, make the road surface form oil and wrap shape or strip.
The objective of the invention is to design a kind of high-temperature stability of using old asphalt pavement to have new bituminous pavement after treatment, the old asphalt pavement regeneration revivifier of low-temperature cracking-resistance.
The present invention realizes like this, at first lipid acid is got a foothold and refine decon, post precipitation gets neat liquid, add carbolineum, turps tankage or petrolatum, heated and stirred to certain temperature is mixed into one and promptly gets the regenerating reactivating agent, wherein the I type formulation weight ratio of being made up of carbolineum, lipid acid tankage, turps tankage or petrolatum is: 0.4-1.0: 0.8-1.2: 0.1-0.4, the II type formulation weight ratio of being made up of carbolineum, lipid acid tankage is 0.6-1.2: 0.8-1.2.
Use this revivifier when old asphalt pavement regeneration revivifier technology of the present invention is overhauled old asphalt pavement, prove all that through chemical analysis, Infrared spectroscopy, physico-mechanical properties test the variation of matter has taken place old bituminous character.It is obvious that the pitch of paraffinic crude refining is improved effect, and the bituminous matter after the regeneration reduces, and fragrance divides and colloid is divided increase, softening temperature reduces, penetration degree increases, and the extension value improves, and the asphalt after the regeneration all improves in mechanical properties such as high-temperature stability, low-temperature cracking-resistances simultaneously.Prove the road surface good stability of the asphalt making after regenerating by large-scale circular track test (B22-100 axle carry 94.5 ten thousand time), rutting resistance is strong.This technical matters flow process is simple, is easy to promote, because the raw material major part is an industry byproduct, it is with low cost.
Below the enforcement of present technique is further described.
I type prescription: 50% lipid acid tankage are refined decon, and post precipitation gets neat liquid, adds 35% carbolineum and 15% turps tankage or petrolatum, and heated and stirred to certain temperature is mixed into one, promptly gets the regenerating reactivating agent.It is broken during use old asphalt pavement to be dug pine, and adds the regenerating reactivating agent after being heated to certain temperature, stirs to spread the road surface and get final product.
II type prescription: get 55% lipid acid tankage and refine decon, precipitate neat liquid, add 45% carbolineum, heated and stirred to certain temperature is mixed into one and promptly gets the agent of II type regenerating reactivating.
Claims (1)
1, a kind of by the old asphalt pavement regeneration revivifier, it is characterized in that this regenerating reactivating agent refines the neat liquid that decon and post precipitation obtain by carbolineum, lipid acid tankage, turps tankage or petrolatum are formed, wherein carbolineum, lipid acid tankage are through refining the neat liquid that the decon post precipitation obtains, and turps tankage or petrolatum weight ratio are: 0.4-1.0,0.8-1.2,0.1-0.4
